Researchers from Monash University in Melbourne have developed a method for determining which genes are "in play" in causing cardiac abnormalities, and the technique not only confirmed well-known congenital heart disease genes, but also discovered 35 new genes not previously suspected in the disease.

An international collaborative study led by Chinese researchers at Wuhan University is the first to have discovered a new small molecule, termed IMA-1, and shown it to be safe and effective for the treatment of nonalcoholic steatohepatitis (NASH) in mouse and macaque models.

Modulation of a single amino acid in the reprogramming factor Kruppel-like factor 4 (KLF4) has been demonstrated to markedly improve natural transcription factor function and to result in faster and more effective reprogramming of somatic cells into induced pluripotent stem cells.

Immunotherapeutic targeting of stage-specific embryonic antigen-4 has been shown to inhibit pancreatic cancer growth in animal models and cancer cell lines, indicating that this approach has promise for treating pancreatic ductal adenocarcinoma and possibly other SSEA-4-positive cancers, according to new a Taiwan/U.S. collaborative study.

Australian researchers have developed a new single-cell expressed barcoding strategy termed SPLINTR (Single-cell Profiling and LINeage TRacing), to investigate the key basic nongenetic transcriptional processes underlying malignant clonal fitness in mouse models of leukemia.

Clonal hematopoiesis of indeterminate potential (CHIP) was associated with a 35% reduced risk of Alzheimer's disease (AD) in studies presented at the plenary session of the American Society of Hematology (ASH) annual meeting on Sunday.

A group of scientists at the Cincinnati Children's Hospital has used separate lines of human induced pluripotent stem cells to create stomach organoids with a three-layered structure and gastric function such as smooth muscle contraction and glandular secretion. The team reported its results in the December 2021, issue of Cell Stem Cell.

A faithful model of the human blastocyst has been developed which replicates key phases of very early development from 4 to 13 days post fertilization, including attaching to layers of hormone-stimulated endometrial cells in vitro, mimicking implantation in the uterus.

Far from the Groundhog Day spectacle of amyloid-targeting antibodies that do little to nothing for patients in trial after trial, researchers have reported success in reducing the risk of Alzheimer’s disease (AD) in unexpected ways. Researchers at the Cleveland Clinic Foundation have discovered that a Viagra prescription was associated with a roughly 70% reduced risk of being diagnosed with AD. And investigators from the University of Washington reported that in the prospective Adult Changes in Thought study, a long-term study into risk and protective factors for dementia, persons who underwent cataract surgery reduced their risk of AD by 30%, an effect that lasted for 10 years after surgery.

In the Dec. 3, 2021, issue of Science, researchers reported that a missense variant that is highly enriched in the Amish population was associated with reduced levels of both LDL cholesterol and fibrinogen. To date, very few variants have been identified that affect more than one risk factor for cardiovascular disease.
